902-152 CrimPro Crimper for RD/YL/BU Insulated terminals - Standard Type, Multicolor

I'm a new comer with electronics, wires, crimpers, you name it. At first I went with a 1890+ reviewed, $20 crimper found here on Amazon that just couldn't keep a secure crimp. A great majority of terminals used in their appropriate receptacle would fail a pull test, and required second crimps or even larger terminals to be placed in smaller slots to work. I cant say exactly why that crimper failed to crimp on the first try; maybe it was me! Safe it say it didn't inspire confidence.Heading to youtube to see if was indeed my crimping method was that incorrect, I stumbled upon a video of an avionics tech using a similar model Pro'sKit crimper. I decided the take a chance on the Pro'sKit 902-152 and was not disappointed. the Pro'sKit jaws are rounded in the "front" and undulated in the "back". The round jaws provide an even crimp against the wires in the terminal barrel, while the back crimp pinches around the wire insulation and securing it. Maybe it's the Pro'sKit's jaw design that was superior to the other crimper's jaws, but now every crimp I made was secure, strong, and I had confidence that I was "doing it right"...the first time!I did notice the more vertical grip aids in ergonomics; your wrist doesn't need to be as nearly as canted down to maintain level jaws compared to the usual "in-line" crimper handles. Crimping with this set feels more natural to me, but your mileage may vary.

I bought one of these and then compared the crimps to one of the $20 or less versions you can buy on here, and this one had a much nicer crimp. The upper part of the crimp where the bare wire is, gets surrounded and sealed tighter, and so does that area around the insulation crimp. I didn't realize my other one was so bad, but after seeing how much better this one was I had to buy 2, for 2 locations.

ok klein is better

I used it for a large job and used it for at least 50-100 crimps. It did the job perfectly.

These are a really good product and produce a good crimp. I'm surprised the seller only has one picture of the crimpers shown on the listing. I bought more expensive ones (Titan) and had to send them back because they didn't produce the right crimp pattern per the IPC standard for insulated terminals. My employer uses the exact same brand and I decided to buy my own pair.

I've used many crimping tools over the years and this is the best ever, especially considering the price and versatility of interchangeable jaws for different applications.I needed a crimper for insulated flag terminals and this tool, with the correct jaws, worked perfect!
